[PATCH v5 0/2] Add Mediatek MT8173 cpufreq driver

[Pi-Cheng Chen]

MT8173 is a ARMv8 based SoC with 2 clusters. All CPUs in a single cluster
share the same power and clock domain. This series tries to add cpufreq support
for MT8173 SoC.

changes in v5:
- Move resource allocation code from init() into probe() and remove some unused
  functions due to this change
- Fix descriptions for device tree binding document
- Address review comments for last version
- Register CPU cooling device

Changes in v4:
- Add bindings for MT8173 cpufreq driver
- Move OPP table back into device tree
- Address comments for last version

Changes in v3:
- Implement MT8173 specific standalone cpufreq driver instead of using
  cpufreq-dt driver
- Define OPP table in the driver source code until new OPP binding is ready

Changes in v2:
- Add intermediate frequency support in cpufreq-dt driver
- Use voltage scaling code of cpufreq-dt for little cluster instead of
  implementaion in notifier of mtk-cpufreq driver
- Code refinement for mtk-cpufreq driver
